I'm currently trying to use the Antenna Array Tool in AMan. After I click "OK" in the dialogue, I am prompted to give the file name and location for the resulting .ffe file. But after I input the name and location and click the "save" button, I cannot find the resulting .ffe file in that location (It seems the file is not written to that location). So I wonder if this is a problem with my operating system or a bug of AMan?
